How true is the duty cycle if you put it at 1% at say 50hz?

[@Manf-ft6zk]

"A 555 on steroids" is a nice description, but I think there are applications for it.
I just have the question whether it starts with the last frequency after power up.

Can use this product for flyback TV CRT?.

[@IMSAIGuy]
